What Pin on the M5StickC-Plus to drive the Spectrum Visualizer LED Matrix?

[LarryXO]

Can't quite figure out in the documentation how to drive the data pin of the LED matrix...can someone point me where I've overlooked it?
Thanks. (Got it loaded on the M5StickC-Plus, now trying to drive the display). Is it the Grove connector?

After some experimentation, it is G26. And if I might digress, I would suggest anyone attempting to build this spend the effort to re-solder everything - my panels had solder blobs randomly across the backs.

Would anyone like the build notes?

The pins are setup in the globals.h file. to help anyone find the for the different projects.
Maybe you could say where you got your panels, I bought some from aliexpress and the quality is fine.
The back of my panels is completely covered in soldermask, except for the connections

Mine were purchased through Dave's Amazon link. There were random solder blobs of a high-temp solder on the back of two of the three units I bought. Almost as if they were soldered in a real hurry, and some splashed. I will likely get my next set from Aliexpress.

Thank you for the comment about the globals.h file. I see them, now.
